Stanislas Wawrinka defending his 2014 title
I think Stanislas Wawrinka will win the 2015 Australian Open because his baseline play cannot be matched by any player on the ATP tour. He showed this with wins over Novak Djokovic and Rafael Nadal in last year’s Australian Open. Wawrinka is one of the weakest movers in contention, but with his strong groundstrokes his opponents are going to be the ones running all over the court. He also may have a weak return of serve, but as long as he can stay away from strong servers like Nick Kyrgios, Kevin Anderson, and John Isner in his draw he should be able to dominate his opponents in route to his second straight Aussie Open victory.
